We have two vmware esx 5.x cluster's: one for internal company and one for customers.
Both are located on our internal network and separated by routers/firewalls.
Currently we did not have any dns in the customer cluster and only used ip.
Now i read it is really advised to have DNS and I am at the process of installing a new vCenter server. I seems I have to options:
use dns in network segment 1 and open firewalls/routers (2x) so that cluster 2 will be able to resolve with DNS.
install second DNS server in cluster 2
use dns forwarding for new DNS domein: nameproduction.company.nl
vm's and hosts will be: host1.nameproduction.company.nl
I am in doubt what is best to do: If I open up firewall for option 1: could heavy traffic etc cause problems with failure situations of vcenter/vmware hosts etc ? Or wouldn't it be a problem ?
Any other tips?
